tap

Hello all, I am trying to use QEMU to emulate a x86_64 machine to run OpenBSD 6.9 inside FreeBSD 12.2-RELEASE with two tap interfaces. Hardware is an Intel Xeon E5450, 8GB DDR2, SATA SSD. This CPU doesn't have EPT support so I can't use bhyve and I don't want to use VirtualBox. I would like, if...

Hello! I've found the issue on my virtual infrastracture. The speed descreases after moving between virtual machines. Hypervisor: OS: FreeBSD 11.2 Application: bhyve Network: bridge+tap Guests: OS: FreeBSD 11.2 Network: vtnet media: Ethernet 10Gbase-T <full-duplex> Traffic flow: INTERNET...

Is it possible to first test a bridge and tap, and maybe even a virtual network interface, before applying it to a VM? I imagine the virtual interface would not be the same one that the VM would create, but, this would be a nice troubleshooting step for getting bridged networking to work on...

I've set MTU to 3000 using the following commands. On hypervisor: ifconfig bridge0 mtu 3000 ifconfig tap0 mtu 3000 ifconfig tap1 mtu 3000 etc. On guests: ifconfig vtnet0 mtu 3000 etc. I've trapped data and get the MSS is 1358. So the above value is not close the 3000. ethertype IPv4...

Hello! I created bridge0 (172.16.0.1) device with few tapX network devices (172.16.0.2-X) (bridged together by bridge0) for bhyve vms. Then I created NAT (pf.conf), that solves networking via wlan0 (wifi card). Why? Because simple bridging doesn't work with wlan0/wifi interfaces (NAT works)...
